- Abstract
The article discusses the planetary location within the solar system in terms of astronomical units. It refers to the lessons taught by the author, which explores several locations in space with the use of celestial coordinating systems, a measurement system similar to Earth-based latitude and longitude. Also discussed is the question on whether or not constellation patterns seen from Earth would look different from another planet in the solar system. It also highlights the discovery of Sedna in 2003, a dwarf planet with approximately 1,200 kilometers in diameter and an orbit around the Sun of about 76 astronomical unit (AU) at perihelion and beyond by roughly 975 AU at aphelion. Moreover, students can explore further the alignment of stars through a free program called Digital Universe.
